BACKGROUND

1. Field of the Disclosure

The present disclosure relates generally to a display device, and moreparticularly, to a display device having an internal antenna device forimplementing a wireless communication function.

2. Description of the Related Art

Wireless communication technologies have recently been implemented invarious manners, such as a wireless local area network (WLAN)represented by a wireless fidelity (Wi-Fi) technology, Bluetooth, nearfield communication (NFC), etc., as well as commercialized mobilecommunication network access. Mobile communication services have evolvedfrom voice call based first-generation mobile communication servicesinto fourth-generation mobile communication networks, thereby makingutilization of the Internet and multimedia services on a mobilecommunication terminal possible. Next-generation mobile communicationservices, which will be commercialized in the future, are expected to beprovided through an ultra-high frequency band of tens of gigahertz (GHz)or more. For example, the majority of mobile communication terminalsthat implement the long term evolution (LTE) technology by the 3GPPstandard, which has been widely used as a representative of thefourth-generation (4G) mobile communication all over the world, mustbasically support a band of 700 megahertz (MHz) to 960 MHz and a band of2.5 GHz to 2.7 GHz.

Further, with the activation of communication standards (such as WLAN,Bluetooth, etc.), electronic devices, for example, mobile communicationterminals, have been equipped with antenna devices that operate indifferent frequency bands. For example, fourth-generation mobilecommunication services may operate in a frequency band of 700 MHz, 1.8GHz, 2.1 GHz, etc.; Wi-Fi may operate in a frequency band of 2.4 GHz and5 GHz but with a slight difference depending on the standardimplemented; and Bluetooth may operate in a frequency band of 2.45 GHz.

Electronic devices require antenna devices in order to make wirelesscommunication possible. The antenna devices are installed with asufficient distance from other devices to prevent the antenna devicesfrom interfering with the other devices when transmitting and receivinghigh frequency signals.

These antenna devices are required to have excellent radiationperformance and a wide band width even within a small volume in order toconform to the design trend of electronic devices that is moving towardslimness and compactness. For example, as antenna areas where internalantenna devices may be embedded in electronic devices have becomenarrower, it is an important issue in antenna design to obtain excellentradiation performance without varying the sizes of the antenna devices.

In cases where antenna devices are embedded in touch panels ofelectronic devices, the electronic devices may be made compact byreducing the spaces where the antenna devices are mounted in theelectronic devices, but the touch functions of the touch panels and theradiation performance of the antenna devices may degrade.

Further, in the cases where antenna devices are embedded in displaydevices of electronic devices, the antenna devices may interfere withthe movement of light within the display devices, thereby deterioratingthe quality of the display devices.

The plurality of pixels 111 a, 111 b, and 111 c may be arranged on afirst substrate 113 with an interval between pixels to form an outputlayer. The pixels 111 a, 111 b, and 111 c may output one of red, green,and blue. For example, the pixels 111 a, 111 b, and 111 c may receivelight output from the back-light 104 through the liquid crystal layer102 to output one of red, green, and blue. The pixels 111 a, 111 b, and111 c may include the first pixels 111 a that output red, the secondpixels that output green, and the third pixels 111 c that output blue.The first pixels 111 a may be arranged with a first interval 113 a awayfrom the second pixels 111 b. The second pixels 111 b may be arrangedwith a second interval 113 b away from the third pixels 111 c. The firstinterval 113 a and the second interval 113 b may be equal to each other,but without being limited thereto, may differ from each other.

The liquid crystal layer 102 may be disposed on the pixels 111 a, 111 b,and 111 c. The liquid crystal layer 102 may have liquid crystalsoriented in a predetermined direction, and which may be oriented in adifferent direction by an electrical signal. The liquid crystal layer102 may change a travel direction of light transmitted to the liquidcrystal layer 102 according to a change in the orientation of the liquidcrystals.

The antennaradiator 105 may be located in the layer that is formed by the pixels111 a, 111 b, and 111 c. The antenna radiator 105 may receive electricalpower to form at least one resonant frequency. The antenna radiator 105may not affect the colors output from the pixels 111 a, 111 b, and 111c, because the conductors of the antenna radiator 105 are arrangedbetween the pixels 111 a, 111 b, and 111 c. In addition, since theconductors of the antenna radiator 105 are arranged between the pixels111 a, 111 b, and 111 c, the antenna radiator 105 may not need to beseparately mounted within the electronic device 10 that includes thedisplay device 100, which makes it possible to make the electronicdevice 10 more compact.

Further, the resonant frequency band of the antenna radiator 105 may bedetermined according to the resistivity, length (1), and line width (w)of the conductors. For example, the resistance of each conductor may beproportional to the resistivity and length thereof, and may be inverselyproportional to the line width thereof.

The antenna radiator 105 may form a resonant frequency band that isinversely proportional to the resistance of the conductors. For example,the antenna radiator 105 may form a high resonant frequency band whenthe conductors have a low resistance. By regulating the resistance ofthe conductors, it is possible to set the frequency band of the antennaradiator 105 within the display device 100.
